Description

【０００１】
【発明の属する技術分野】
本発明は、食品包装用のラップフィルムやアルミホイルなどを巻回した巻筒体の収納箱に関する。特に、巻筒体の引き出し易さと、飛び出し防止性能と、巻筒体の箱からの取り出し易さを調和させた巻筒体の収納箱に関する。
【０００２】
【従来の技術】
ラップフィルムやアルミホイルは芯体に巻回された巻筒体が箱に収納されており、使用時に必要量引き出すようになっている。その際、巻筒体が箱内で滑らかに回転しなかったり、引き出す力により箱外へ飛び出すことがあった。これらを防止する手段としては、例えば実開昭５６−９４７２１号公報は箱体の側面に芯管枢支片を形成し、箱体の両端から芯管枢支片を芯管内部へ押し込み、同時に固定片、受止片、制止片等の補助部材を用いることで芯管枢支片を固定し芯管が箱から飛び出すのを防止する方法が開示されている。又、実開昭６０−５７５１９号公報では、コア内部に押し込んだ抜け止め片を完全に固定することなくロール状物の飛び出しを防止する方法が開示されている。又、特開平１０−３３８２２８号公報では、支持部材の寸法等を規定して、巻筒体が収納室から飛び出すのを防止すると共に、特に巻筒体の筒体径を小さくして長尺巻としたラップフィルムやアルミホイルが、使用と共に消費されて巻筒体の外径が底板の奥行き幅よりも十分に小さくなった時に発生し易い引き出し時の遊回動も防止する方法が開示されている。
【０００３】
【発明が解決しようとする課題】
しかしながら上記した実開昭５６−９４７２１号公報のように芯管枢支片が芯管内部に固定されている技術は、芯管の飛び出しを防止する効果は十分であるが、使用中のトラブル、例えばフィルムの先端部を見つけられなくなり、芯管を箱から取り出す必要が生じた時などは、非常に取り出し難く無理矢理取り出そうとした場合には芯管枢支片が破損するという問題がある。更に、芯管内壁に強固に芯管枢支片が接触しているため芯管を係止した状態でフィルムを引き出す際にそれが抵抗になり引き出すのに大きな力が必要になる。
【０００４】
又、実開昭６０−５７５１９号公報のように抜け止め片が固定されていない技術のものは、ロール状物の取り出し時に抜け止め片が破損する問題はほとんど発生しないが、押し込んだ抜け止め片に強度がないため勢い良く引き出した時には抜け止め片が脇板に対し９０度以上折れ曲がり、ロール状物の飛び出しを十分に防止できないという問題がある。
又、特開平１０−３３８２２８号公報の技術では、筒体内径と支持部材の最大幅の比率が１に近いため、飛び出し防止能力と遊回動防止能力は高いが、使用中のトラブル時等に巻筒体を抜き出すのに大きな力が必要になる。
本発明は、このような従来の巻筒体の飛び出しを防止する手段が抱えている問題、つまり巻筒体の飛び出し防止性能と、巻筒体の箱からの取り出し易さを調和させた上で引き出し性にも問題が無く、外観に破損が無い巻筒体の収納箱を提供することを目的とする。

【課題を解決するための手段】
本発明者らは、上記課題を達成するために鋭意検討した結果、本発明をなすに至った。すなわち本発明は以下の通りである。
前板１、底板２、後板３、及び脇板８、補助脇板９、９′の各面で形成される上部が開口した収納室１２と、その収納室１２の後板３の上端縁から開閉可能で収納室１２を覆う方向に連接した蓋板４と、その蓋板４の前端縁から前板１を覆う方向に延出した掩蓋片５と、掩蓋片脇板１０、掩蓋片補助脇板１１の各面で形成される蓋体１３からなる直方体の箱体と、上記収納室１２に収納される巻筒体Ｒからなり、補助脇板９には折り線ｇを介して巻筒体Ｒの内部へ挿入可能で巻筒体Ｒを支持するための舌片状の支持部材１５′が形成され、脇板８には折り線ｇ又は半切れ線ｇ１を介して収納室内部へ押し込み可能で支持部材１５′を巻筒体Ｒの内部へ挿入させるための窓１５が形成された巻筒体収納箱において、底板２の奥行き幅がＷａ、後板３の幅がＷｂ、芯体Ｒ１の幅と内径と厚みが各々ＷｃとＤとｔ、支持部材１５′の折り線幅と最大幅が各々ＳとＬ、窓１５の最大高さがＨ１とした時に、次の１〜４式の条件を満たす巻筒体収納箱。
【０００７】
０．８２Ｗａ＜（Ｄ＋２ｔ）＜Ｗａ１式
０．４≦Ｌ／Ｄ≦０．７２式
０．５≦Ｓ／Ｌ≦１３式
（Ｗｂ−Ｗｃ）≦Ｈ１≦２（Ｗｂ−Ｗｃ）４式
本発明が従来技術と最も相違するところは、従来技術が各種の形状の支持部材を箱体の両端から芯体の内部に、単に押し込むだけか予め押し込んだ状態で固定するものであるのに対し、本発明は、（１）底板２の奥行き幅Ｗａに対する芯体Ｒ１の外径（Ｄ＋２ｔ）の範囲、（２）芯体Ｒ１の内径Ｄに対する支持部材１５′の最大幅Ｌの比率の範囲、（３）支持部材１５′の最大幅Ｌに対する折り線幅Ｓの比率の範囲、（４）巻筒体Ｒを収納室に収納した場合の長手幅方向の隙間（Ｗｂ−Ｗｃ）に対する窓１５の最大高さＨ１の範囲を特定したことである。
【０００８】
上記従来技術と相違するところの本発明の構成要件の役割は、巻筒体の飛び出し防止能力と収納箱からの取り出し易さを調和させた上で引き出し性にも問題が無く、外観に破損が無い巻筒体の収納箱を提供することである。
以下、図を用いて本発明を更に詳細に説明する。図１は本発明による巻筒体収納箱の支持部材１５′が巻筒体Ｒの内部に押し込まれた状態を示す立体模式図の一例である。図２は図１に示した巻筒体収納箱の展開図である。図３は収納室１２に巻筒体Ｒを入れてフィルムＦを引き出した状態を上から見た模式図である。図４は芯体Ｒ１と支持部材１５′の関係を示す断面図である。図５は支持部材１５′の別の形状を示した一例である。本発明において最大幅Ｌとは収納箱の高さ方向と直交する方向の支持部材１５′の最大寸法を示し、最大高さＨ１とは収納箱の高さ方向での窓１５の最大寸法を示す。
【０００９】
本発明の一例を示す図１において、収納箱は前板１、底板２、後板３、及び脇板８、補助脇板９、９′の各面で形成される上部が開口した収納室１２と、その収納室１２の後板３の上端縁から開閉可能で収納室１２を覆う方向に連接した蓋板４と、その蓋板４の前端縁から前板１を覆う方向に延出した掩蓋片５と、掩蓋片脇板１０、掩蓋片補助脇板１１の各面で形成される蓋体１３からなる直方体の箱体である。尚、図１、図２、図４には前板１の上端縁に縁折り片７を設けて図１では折り曲げた状態を示しているが、この縁折り片７は設けなくても良いし、或いは１８０度折り曲げて前板１の裏面と接着させても構わない。
【００１０】
この収納箱には、フィルムＦを切断するための切断具Ｋが配備され、収納室１２に収納された巻筒体Ｒから必要量フィルムを引き出し切断して使用される。切断具の形状は、直線状、Ｖ状等、材質も金属、バルカナイズドファイバー等従来公知のものであれば特に制限はない。又、切断具が配備されている部位は、図１に示す掩蓋片５の先端縁部、前板１の上端縁部、底板と前板の間の稜線部いずれでも構わない。
本発明の巻筒体収納箱において、底板２の奥行き幅Ｗａに対する芯体Ｒ１の外径（Ｄ＋２ｔ）の範囲は、０．８２Ｗａ＜（Ｄ＋２ｔ）＜Ｗａ（１式）である。（Ｄ＋２ｔ）≦０．８２Ｗａの場合は底板２の奥行き幅Ｗａに対して芯体Ｒ１の外径（Ｄ＋２ｔ）が小さいので、フィルム等が使用と共に消費されて巻筒体が細くなった時に巻筒体が収納室で遊回動を発生し易く使い勝手が悪くなる。（Ｄ＋２ｔ）≧Ｗａの場合は巻筒体を収納室に収納することができない。
【００１１】
本発明の支持部材１５′は折り線ｇを介して脇板上辺とほぼ平行に設けられており、その最大幅Ｌと芯体Ｒ１の内径Ｄの関係は０．４≦Ｌ／Ｄ≦０．７（２式）である。図１に示したようにこの範囲にある支持部材１５′が芯体Ｒ１の内部に挿入された場合は、使用者がフィルムを引き出した時に巻筒体が箱外に飛び出す現象を防止することができると同時に、使用者が何らかの理由で収納室から巻筒体を取り出そうとする操作に過剰な力が不要であり、支持部材の破損も発生しない。これは、巻筒体の飛び出し防止性能と取り出し易さが支持部材１５′の最大幅Ｌと芯体Ｒ１の内径Ｄとの関係に大きく依存しており、その関係が０．４≦Ｌ／Ｄ≦０．７の場合に巻筒体の飛び出し防止性能と取り出し易さが最も調和されるためである。
【００１２】
Ｌ／Ｄ＜０．４の場合は、芯体の内径Ｄに対して支持部材の最大幅Ｌが小さいため、巻筒体を取り出し易いが、フィルムの引き出し時に巻筒体が飛び出し易くなる問題がある。また、Ｌ／Ｄ＞０．７の場合は、芯体の内径Ｄに対して支持部材の最大幅Ｌが大きいため、フィルムの引き出し時に巻筒体は飛び出し難いが、巻筒体が取り出し難くなる問題がある。尚、最大幅Ｌは図２のように折り線ｇから離れていても、図５（ｂ）のように重なっていても構わないが、最大幅Ｌの配置は折り線ｇからＷｂ−Ｗｃ以上離れた所に設けることにより、一般的に使用されている紙製芯体の内部端にある凹凸と支持部材１５′の端面が接触することがなくなり、巻筒体が抵抗なく回転するのでが好ましい。
【００１３】
更に、支持部材の最大幅Ｌと直交する最大高さＨについては特に規定しないが、支持部材の最大高さＨは０．６Ｌ≦Ｈ≦Ｌの範囲とすると、支持部材と芯体内部との引っ掛かり具合が十分となるので、フィルムの引き出し時に巻筒体が飛び出しにくくなる上、支持部材を押し込んだ時に支持部材の下端と芯体端が接触することがなく、芯体空間内への押し込みがスムーズとなる点で好ましい。また、上述の条件を満たす限り、支持部材の形状は曲線の組み合わせ型、半円型、台形型、矢印型等の任意の形状で構わない。
【００１４】
次に、支持部材１５′の最大幅Ｌと折り線幅Ｓの関係は０．５≦Ｓ／Ｌ≦１（３式）である。これは巻筒体の飛び出し防止性能と取り出し易さの調和が支持部材の最大幅Ｌと芯体の内径Ｄの関係（２式）と共に、最大幅Ｌと折り線幅Ｓの関係にも依存していることを示している。Ｓ／Ｌ＜０．５の場合は最大幅Ｌに対して折り線幅Ｓが小さいので巻筒体の取り出し易さには問題がないが、飛び出し防止能力が不十分となる。また、本発明の巻筒体収納箱では支持部材１５′の最大幅をＬと定義しているので、Ｓ／Ｌ＞１となることはない。
次に、窓１５の最大高さＨ１と後板３の幅Ｗｂと芯体Ｒ１の幅Ｗｃの関係は（Ｗｂ−Ｗｃ）≦Ｈ１≦２（Ｗｂ−Ｗｃ）（４式）である。これは図３で示したように、収納室１２に巻筒体Ｒを収納した場合の幅方向の隙間と窓５の最大高さＨ１の関係を示している。Ｈ１がこの範囲にあるものは、収納箱の外観と巻筒体の取り出し易さが調和している。
【００１５】
Ｈ１＜（Ｗｂ−Ｗｃ）の場合は、巻筒体を収納室から取り出す時に窓１５が芯体内部に引っ掛かからないので巻筒体の取り出し易さを阻害することはないが、Ｈ１が小さいため生産時にピン等で窓を綺麗に押し込むことが困難で、窓自体がちぎれたり脇板８の窓周辺に破れ等を発生して収納箱の外観が著しく低下する可能性がある。また、Ｈ１＞２（Ｗｂ−Ｗｃ）の場合は、生産時にピン等で窓１５を押し込んでも外観に問題はないが、Ｈ１が大きいため巻筒体を取り出す時に窓１５自体が芯体内部に引っ掛かって巻筒体の取り出し易さが阻害される。尚、窓１５の最大幅Ｌ１と窓１５自体の配置位置と形状については特に規定しないが、図４に示したようにＬ１については生産時にピン等で押し込んだ場合に外観悪化を生じない程度に大きく、図４に示したように収納箱を組み立てた時に窓１５全体が支持部材１５′の範囲内に収まる程度に小さい長さとすれば良い。配置位置についても図４に示したように、収納箱を組み立てた時に底板２端部から窓１５の折り線ｇ又は半切れ線ｇ１までの長さと底板２端部から支持部材１５′の折り線ｇまでの長さがほぼ同じとなるように配置させる事が好ましい。形状については上述した条件を満たせば任意の形状で構わないが、四角形型が好ましい。
【００１６】
本発明の収納箱に使用される材質としては、板紙、各種ダンボール、プラスチックス等特に制限はないが、一般的には厚さ０．３５ｍｍ〜１．５ｍｍの板紙が使用される。本発明の収納箱に収納される巻筒体に巻き回されるフィルムは、各種樹脂製のラップフィルム、アルミホイル、クッキングペーパー等特に制限はないが、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリエチレン等のラップフィルムが特に好ましい。

BACKGROUND OF THE INVENTION
The present invention relates to a storage box for a wound tubular body in which a wrap film for food packaging, aluminum foil, or the like is wound. In particular, the present invention relates to a storage box for a winding cylinder that harmonizes the ease of pulling out the winding cylinder, the pop-out prevention performance, and the ease of taking out the winding cylinder from the box.
[0002]
[Prior art]
A wrap film or aluminum foil is wound around a core and is housed in a box so that a necessary amount can be pulled out during use. At that time, the winding cylinder may not rotate smoothly inside the box or may jump out of the box due to the pulling force. As means for preventing these, for example, Japanese Utility Model Laid-Open No. 56-94721 forms a core tube pivot piece on the side of the box, and pushes the core tube pivot piece into the core tube from both ends of the box. A method is disclosed in which the core tube pivotal support piece is fixed by using auxiliary members such as a fixing piece, a receiving piece, a restraining piece, and the core tube is prevented from jumping out of the box. Japanese Utility Model Laid-Open No. 60-57519 discloses a method for preventing the roll-like material from popping out without completely fixing the retaining piece pushed into the core. In Japanese Patent Laid-Open No. 10-338228, the size of the support member is specified to prevent the winding cylinder from jumping out of the storage chamber, and in particular, the cylindrical diameter of the winding cylinder is reduced to make a long winding. A method of preventing loose rotation during pulling that is likely to occur when the wrap film or aluminum foil is consumed with use and the outer diameter of the winding cylinder is sufficiently smaller than the depth width of the bottom plate is disclosed. Yes.
[0003]
[Problems to be solved by the invention]
However, the technique in which the core tube pivot support piece is fixed inside the core tube as described in Japanese Utility Model Publication No. 56-94721 is sufficient in preventing the core tube from popping out, but troubles during use, For example, when it becomes impossible to find the leading end of the film and it becomes necessary to take out the core tube from the box, there is a problem that the core tube pivot piece is damaged if it is difficult to take out and the force is taken out. Furthermore, since the core tube pivot support piece is firmly in contact with the inner wall of the core tube, when the film is pulled out while the core tube is locked, it becomes a resistance and a large force is required to pull out the film.
[0004]
Further, the technology in which the retaining piece is not fixed as in Japanese Utility Model Publication No. 60-57519 hardly causes the problem that the retaining piece is damaged when the roll-shaped object is taken out. However, when it is pulled out vigorously, there is a problem that the retaining piece bends 90 degrees or more with respect to the side plate and the roll-like object cannot be prevented from popping out sufficiently.
In the technique disclosed in Japanese Patent Laid-Open No. 10-338228, the ratio of the inner diameter of the cylindrical body and the maximum width of the support member is close to 1, so that the pop-out prevention ability and the free rotation prevention ability are high. A large force is required to extract the winding cylinder.
The present invention harmonizes the problem that the conventional means for preventing the winding cylinder from popping out, that is, the ability to prevent the winding cylinder from jumping out and the ease of taking out the winding cylinder from the box. It is an object of the present invention to provide a storage case of a wound tubular body that has no problem in drawability and is not damaged in appearance.

[Means for Solving the Problems]
As a result of intensive studies to achieve the above-mentioned problems, the present inventors have made the present invention. That is, the present invention is as follows.
The front plate 1, the bottom plate 2, the rear plate 3, the side plate 8 and the auxiliary side plates 9 and 9 'formed in the respective surfaces of the storage chamber 12 opened at the top, and the upper edge of the rear plate 3 of the storage chamber 12 A lid plate 4 that can be opened and closed from the front and connected in a direction covering the storage chamber 12; a lid lid piece 5 extending from the front edge of the lid plate 4 in a direction covering the front plate 1; a lid lid side plate 10; It consists of a rectangular parallelepiped box formed of a lid 13 formed on each side of the side plate 11 and a winding cylinder R stored in the storage chamber 12, and the auxiliary side plate 9 is wound on the auxiliary side plate 9 via a folding line g. A tongue-like support member 15 'that can be inserted into the body R and supports the winding cylinder R is formed, and the side plate 8 is pushed into the storage chamber through the folding line g or the half-cut line g1. In the winding cylinder storage box in which the window 15 for allowing the support member 15 ′ to be inserted into the winding cylinder R is formed, the depth width of the bottom plate 2 is Wa, and the rear 3 is Wb, the width, the inner diameter and the thickness of the core R1 are Wc, D and t, the folding line width and the maximum width of the support member 15 'are S and L, respectively, and the maximum height of the window 15 is H1. Sometimes, a wound cylinder storage box that satisfies the following formulas 1 to 4.
[0007]
0.82 Wa <(D + 2t) <Wa Formula 1 0.4 ≦ L / D ≦ 0.7 Formula 2 0.5 ≦ S / L ≦ 1 Formula 3 (Wb−Wc) ≦ H1 ≦ 2 (Wb−Wc) 4 Formula The present invention is most different from the prior art in that the prior art fixes the various shapes of support members from both ends of the box body into the core body either simply by pushing them in or in a pre-pressed state. On the other hand, in the present invention, (1) the range of the outer diameter (D + 2t) of the core body R1 with respect to the depth width Wa of the bottom plate 2, and (2) the range of the ratio of the maximum width L of the support member 15 'to the inner diameter D of the core body R1. (3) The range of the ratio of the folding line width S to the maximum width L of the support member 15 ′, (4) the window 15 for the gap (Wb−Wc) in the longitudinal width direction when the winding cylinder R is stored in the storage chamber. The range of the maximum height H1 is specified.
[0008]
The role of the constituent elements of the present invention, which is different from the above prior art, is that the ability to prevent the winding tube from popping out and the ease of taking out from the storage box are harmonized , and there is no problem in the drawability, and the appearance is damaged. It is to provide a storage box with no winding cylinder.
Hereinafter, the present invention will be described in more detail with reference to the drawings. FIG. 1 is an example of a three-dimensional schematic diagram showing a state in which the support member 15 ′ of the wound tube storage box according to the present invention is pushed into the wound tube R. FIG. 2 is a development view of the wound cylinder storage box shown in FIG. FIG. 3 is a schematic view of the state in which the winding cylinder R is put into the storage chamber 12 and the film F is pulled out, as viewed from above. FIG. 4 is a cross-sectional view showing the relationship between the core body R1 and the support member 15 '. FIG. 5 shows an example of another shape of the support member 15 '. In the present invention, the maximum width L indicates the maximum dimension of the support member 15 'in the direction orthogonal to the height direction of the storage box, and the maximum height H1 indicates the maximum dimension of the window 15 in the height direction of the storage box. .

In FIG. 1 showing an example of the present invention, the storage box has a front plate 1, a bottom plate 2, a rear plate 3, a side plate 8 and auxiliary side plates 9 and 9 'formed on the respective surfaces of the auxiliary side plates 9 and 9'. A lid plate 4 that can be opened and closed from the upper end edge of the rear plate 3 of the storage chamber 12 and that is connected in a direction covering the storage chamber 12, and a lid that extends from the front end edge of the lid plate 4 in a direction covering the front plate 1 It is a rectangular parallelepiped box made up of a piece 5 and a lid 13 formed on each side of the lid cover piece side plate 10 and the lid cover piece auxiliary side plate 11. 1, 2, and 4 show a state in which the edge folding piece 7 is provided at the upper edge of the front plate 1 and is bent in FIG. 1, the edge folding piece 7 may not be provided. Alternatively, it may be bent 180 degrees and bonded to the back surface of the front plate 1.
[0010]
In this storage box, a cutting tool K for cutting the film F is provided, and a necessary amount of film is drawn out from the winding cylinder R stored in the storage chamber 12 and used. The shape of the cutting tool is not particularly limited as long as it is a conventionally known one such as a straight shape, a V shape, and the material is a metal, a vulcanized fiber, or the like. Moreover, the site | part by which the cutting tool is arrange | positioned may be either the front-end edge part of the lid cover piece 5 shown in FIG. 1, the upper end edge part of the front board 1, and the ridgeline part between a bottom board and a front board.
In the wound tube storage box of the present invention, the range of the outer diameter (D + 2t) of the core body R1 with respect to the depth width Wa of the bottom plate 2 is 0.82Wa <(D + 2t) <Wa (1 type). In the case of (D + 2t) ≦ 0.82 Wa, the outer diameter (D + 2t) of the core body R1 is smaller than the depth width Wa of the bottom plate 2. Therefore, when the film is consumed with use and the winding cylinder becomes thin, the winding cylinder It is easy for the body to generate free rotation in the storage room, and the usability is poor. When (D + 2t) ≧ Wa, the wound cylinder cannot be stored in the storage chamber.
[0011]
The support member 15 'of the present invention is provided substantially parallel to the upper side of the side plate via the folding line g, and the relationship between the maximum width L and the inner diameter D of the core body R1 is 0.4 ≦ L / D ≦ 0. 7 (2 formulas). As shown in FIG. 1, when the support member 15 'within this range is inserted into the core R1, it is possible to prevent the winding cylinder from jumping out of the box when the user pulls out the film. At the same time, an excessive force is not required for the user's operation to take out the winding cylinder from the storage chamber for some reason, and the support member is not damaged. This is because the ability to prevent the winding tube from popping out and the ease of taking it out greatly depend on the relationship between the maximum width L of the support member 15 'and the inner diameter D of the core R1, and the relationship is 0.4 ≦ L / D. This is because, when ≦ 0.7, the roll-out prevention performance of the winding cylinder and the ease of taking out are most harmonized.
[0012]
When L / D <0.4, the maximum width L of the support member is small with respect to the inner diameter D of the core body, so that the winding cylinder body can be easily taken out, but the winding cylinder body tends to pop out when the film is pulled out. is there. Further, when L / D> 0.7, the maximum width L of the support member is larger than the inner diameter D of the core, so that the winding cylinder is difficult to jump out when the film is pulled out, but the winding cylinder is difficult to take out. There's a problem. The maximum width L may be separated from the fold line g as shown in FIG. 2 or overlapped as shown in FIG. 5B, but the arrangement of the maximum width L is Wb−Wc or more from the fold line g. By providing it at a distant place, it is preferable that the irregularities at the inner end of a commonly used paper core and the end surface of the support member 15 ′ do not come into contact with each other, and the winding cylinder rotates without resistance. .
[0013]
Further, although the maximum height H orthogonal to the maximum width L of the support member is not particularly defined, if the maximum height H of the support member is in a range of 0.6L ≦ H ≦ L, the support member and the inside of the core body Since the hooking condition is sufficient, it is difficult for the winding cylinder to pop out when the film is pulled out, and when the support member is pushed in, the lower end of the support member and the core end do not come into contact with each other, so that the push-in into the core space is prevented. It is preferable in terms of smoothness. In addition, as long as the above-described conditions are satisfied, the shape of the support member may be any shape such as a combination type of curves, a semicircular shape, a trapezoidal shape , and an arrow shape.
[0014]
Next, the relationship between the maximum width L of the support member 15 ′ and the folding line width S is 0.5 ≦ S / L ≦ 1 (3 formulas). This depends on the relationship between the maximum width L and the folding line width S as well as the relationship between the maximum width L of the support member and the inner diameter D of the core body (formula 2). It shows that. In the case of S / L <0.5, the folding line width S is smaller than the maximum width L, so that there is no problem in the ease of taking out the wound cylindrical body, but the pop-out preventing ability is insufficient. Further, in the wound tubular body storage box of the present invention, since the maximum width of the support member 15 'is defined as L, S / L> 1 is not satisfied.
Next, the relationship between the maximum height H1 of the window 15, the width Wb of the rear plate 3, and the width Wc of the core R1 is (Wb−Wc) ≦ H1 ≦ 2 (Wb−Wc) (4 formulas). This shows the relationship between the gap in the width direction and the maximum height H1 of the window 5 when the winding cylinder R is stored in the storage chamber 12, as shown in FIG. In the case where H1 is in this range, the appearance of the storage box and the ease of taking out the wound cylinder are harmonized.
[0015]
In the case of H1 <(Wb−Wc), since the window 15 is not caught inside the core body when the winding cylinder is taken out from the storage chamber, the ease of taking out the winding cylinder is not hindered, but H1 is small. It is difficult to push the window neatly with a pin or the like during production, and the window itself may be torn off or torn around the window of the side plate 8 to significantly reduce the appearance of the storage box. In the case of H1> 2 (Wb-Wc), there is no problem in appearance even if the window 15 is pushed in with a pin or the like during production. However, since H1 is large, the window 15 itself is caught inside the core body when the winding cylinder is taken out. This hinders the ease of taking out the winding cylinder. The maximum width L1 of the window 15 and the position and shape of the window 15 itself are not particularly defined. However, as shown in FIG. 4, the appearance of L1 does not deteriorate when it is pushed in with a pin or the like during production. The length may be large and small enough to fit the entire window 15 within the range of the support member 15 'when the storage box is assembled as shown in FIG. As for the arrangement position, as shown in FIG. 4, when the storage box is assembled, the length from the end of the bottom plate 2 to the fold line g or half cut line g1 of the window 15 and the fold line of the support member 15 'from the end of the bottom plate 2 It is preferable to arrange them so that the lengths up to g are substantially the same. The shape may be any shape as long as the above-described conditions are satisfied, but a rectangular shape is preferable.
[0016]
The material used for the storage box of the present invention is not particularly limited, such as paperboard, various corrugated cardboards, plastics, etc., but generally a paperboard having a thickness of 0.35 mm to 1.5 mm is used. The film wound around the winding cylinder stored in the storage box of the present invention is not particularly limited, such as wrap film made of various resins, aluminum foil, cooking paper, etc., such as polyvinyl chloride, polyvinylidene chloride, polyethylene, etc. A wrap film is particularly preferred.
Next, the evaluation method and scale used in the present invention are shown below.

This winding cylinder storage box was handed to 10 female monitors, and each person pulled out and cut about 30 cm of film at a time until the film disappeared. When the number of monitors who answered that the film could be pulled out smoothly was 10 (circle) (excellent drawability), 7-9 (triggered but not adopted), 6 or less X (impractical).
[0018]
<Prevention of popping out> The number of times the winding tube jumped out during the pullout monitor was counted. ○ (Excellent pop-out prevention) when 10 monitors answered that the number of pop-outs was zero. △ (Practical but not adopted) when less than 3 monitors responded that popped out more than once. The case of 3 or more people was set as x (impractical).
<< Extractability >> The support member 15 'is damaged when a cylindrical storage box is prepared in the same manner as the evaluation of the pull-out property and each monitor grasps the central part of the cylindrical tube in the storage box and removes it from the box. ○ When the number of monitors who answered that the winding tube body could be easily removed was 10 (excellent takeout property), when the support member 15 'was broken or large resistance was generated, (Not practical).
[0019]
